The hoistway 5 is provided with a car 6, a counterweight 7, a main rope 8 connecting the car 6 and the counterweight 7, a guide rail 9, and an end point switch 10.

The car 6 is provided with a door drive device 11. The door driving device 11 includes a door motor for driving the car door provided in the car 6, an encoder for detecting the rotational position of the door motor, and a fully closed detector for detecting that the car door is completely closed. Further, a car operation panel 12 is provided in the car 6. A landing operation panel 14 is provided at the landing 13. A shock absorber 16 is provided in the pit 15.

The car controller 18 is provided in the car 6, and more specifically, for example, the car controller 18 is provided on the car 6. The car controller 18 is connected to the control panel 3 by a moving cable 17. In the car controller 18, the door drive device 11, the car operation panel 12, the ceiling device (not shown) provided on the ceiling of the car 6, and the car 6 landed on the landing 13 by a cable (not shown). It is connected to a landing detection device (not shown) or the like that detects. The ceiling device is, for example, a lighting device provided on the ceiling of the car 6. The car controller 18 controls the connected equipment according to the instruction received from the control panel 3. Specifically, for example, the car controller 18 opens and closes the car door by controlling the door driving device 11 according to an instruction received from the control panel 3.

Here, the device related to the car 6 is called a car device. Specific examples of such a car device include a car controller 18, a door drive device 11, a car operation panel 12, a moving cable 17, a ceiling device, a landing detection device, and the like. Further, the equipment related to the landing 13 is referred to as a landing equipment. Specific examples of such landing equipment include a landing operation panel 14. Further, the equipment related to the hoistway 5 is called a hoistway equipment. Specific examples of such hoistway equipment include an end point switch 10, a hoistway cable (not shown), and the like. Hereinafter, the landing equipment and the hoistway equipment will be referred to as the landing / hoistway equipment.

Next, the split construction steps to be performed during the elevator renewal construction period will be described with reference to FIG. FIG. 2 is a table showing an example of a series of divided construction steps of the elevator renewal method according to the first embodiment of the present invention.

Here, in order to shorten the continuous suspension period of the elevator during the elevator renewal work period, the renewal work is divided into a plurality of divided work steps. Each division construction step is completed within a time that can be continuously secured, and the user can use the elevator after each division construction step is completed. That is, in order to shorten the continuous suspension period of the elevator during the renewal construction period of the elevator, it is a prerequisite that the elevator can be used at the end of each division construction step. For example, it is necessary to make the elevator available in the morning and evening hours when there are many users such as commuting to work and school in condominiums, and in the business hours such as evening and night in restaurant tenant buildings.

Therefore, when renewing at least a part of the equipment of the elevator, the contents of the renewal are divided into a series of divided construction steps in units where the elevator can be normally operated after the completion of each divided construction step. .. Renewal work is carried out according to this series of division work steps. As shown in FIG. 2, the content of the renewal work is divided into, for example, three split construction steps, a split construction step S1 to a split construction step S3. However, depending on the specifications of the elevator, it may be necessary to further divide each division construction step.

In the split construction step S1, a new control panel is installed in addition to the existing control panel. Subsequently, the existing old hoisting machine, which is an example of the first old equipment, will be renewed. The main equipment to be renewed in the split construction step S1 is a control panel, a hoisting machine, a main rope, a weighing device, and the like. After the completion of the split construction step S1, the elevator is in a state where it can be normally operated.

In the split construction step S2, the existing old car equipment, which is an example of the second old equipment, is renewed. The split construction step S2 is performed after the split construction step S1. The main devices to be renewed in the split construction step S2 are a car controller, a door drive device, a car operation panel, a moving cable, a ceiling device, a landing detection device, and the like. After the completion of the split construction step S2, the elevator is in a state where it can be normally operated.

In the split construction step S3, the existing old landing / hoistway equipment, which is an example of the third old equipment, is renewed. The split construction step S3 is performed after the split construction step S2. The main equipment to be renewed in the split construction step S3 is a landing operation panel, an end point switch, a hoistway cable, and the like. After the completion of the split construction step S3, the elevator is in a state where it can be normally operated.

In this way, when one of the series of split construction steps is completed, the elevator is in a state where it can be normally operated. Therefore, when one division construction step is completed, a time zone in which the user can use the elevator is created, and the continuous suspension period of the elevator can be shortened.

(Renewal method)
Next, the method of renewing the elevator according to the first embodiment will be described with reference to FIGS. 3 to 7. FIG. 3 is a block diagram showing an initial state of an elevator device to which the elevator renewal method according to the first embodiment of the present invention is applied.

As shown in FIG. 3, the existing old control panel 100 includes an old control board 110 which is a control board for controlling an elevator device. In the initial state of the elevator device, the old control board 110 of the old control panel 100 is connected to each of the existing old hoisting machine 200, the existing old car equipment 300, and the existing old landing / hoistway equipment 400.

The communication method applied to the old control board 110 is, for example, a serial communication method. Hereinafter, the communication method applied to the old control board 110 will be referred to as an "old communication method". The old control board 110 controls the elevator device by communicating with each of the old hoisting machine 200, the old car device 300, and the old landing / hoistway device 400 by the old communication method.

(Split construction step S1: Control panel installation / hoisting machine renewal)
Next, the split construction step S1 will be described with reference to FIG. FIG. 4 is a block diagram showing a state of the elevator device after performing the division construction step S1 with respect to the initial state of the elevator device of FIG.

In the split construction step S1, a step of installing the new control panel 100A at a position different from the old control panel 100 is carried out in the machine room. The new control panel 100A includes a new control board 110A which is a control board for controlling the elevator device. By carrying out this step, the old control panel 100 and the new control panel 100A will be mixed.

Subsequently, a step of replacing the old control board 110 of the old control panel 100 with the communication conversion board 120 is carried out. Specifically, in this step, the old control board 110 is removed from the old control board 100, and the communication conversion board 120 is attached to the old control board 100. By carrying out this step, the old control panel 100 will include the communication conversion board 120. The size of the old control board 110 is, for example, the same as the size of the communication conversion board 120.

Subsequently, a step of connecting the new control board 110A of the new control panel 100A and the communication conversion board 120 of the old control panel 100 is carried out. Subsequently, a step of connecting the communication conversion board 120 of the old control panel 100 and each of the old car device 300 and the old landing / hoistway device 400 is carried out.

Subsequently, the process of renewing the old hoisting machine 200 to the new hoisting machine 200A is carried out. Specifically, in this step, the old hoisting machine 200 is replaced with the new hoisting machine 200A. Subsequently, a step of connecting the new control board 110A of the new control panel 100A and the new hoisting machine 200A is carried out.

The communication method applied to the new control board 110A is, for example, a serial communication method such as a CAN (Control Area Network) communication method. Hereinafter, the communication method applied to the new control board 110A will be referred to as a "new communication method". The new communication method can send and receive a large amount of data than the old communication method, and the data transmission speed is faster than the old communication method. The new control board 110A controls the elevator device by communicating with each of the new hoisting machine 200A, the new car device 300A described later, and the new landing / hoistway device 400A described later by a new communication method.

Next, the configuration of the communication conversion board 120 will be described with reference to FIG. FIG. 5 is a block diagram showing the configuration of the communication conversion board 120 of FIG. The communication conversion board 120 is configured to mutually convert the communication method between the old communication method and the new communication method. Specifically, as shown in FIG. 5, the communication conversion board 120 includes a CPU (Central Processing Unit) 121 and a RAM (Random Access Memory) 122.

The CPU 121 formats and converts the data from the old car device 300 into the data corresponding to the new control board 110A, and stores it in the RAM 122. The format refers to a data structure such as the number of bits. The CPU 121 formats and converts the data from the new control board 110A into data corresponding to the old car device 300, and stores the data in the RAM 122.

The CPU 121 takes out the above-mentioned format-converted data from the RAM 122 and outputs it in response to a request from the new control board 110A. The CPU 121 takes out the format-converted data described above from the RAM 122 and outputs the data in response to a request from the old car device 300. As a result, even if the applied communication method is different, the new control board 110A of the new control panel 100A can communicate with the old car device 300 via the communication conversion board 120.

Similarly, the CPU 121 formats and converts the data from the old landing / hoistway device 400 into the data corresponding to the new control board 110A, and stores it in the RAM 122. The CPU 121 converts the data from the new control board 110A into data corresponding to the old landing / hoistway device 400, and stores it in the RAM 122.

The CPU 121 takes out the above-mentioned format-converted data from the RAM 122 and outputs it in response to a request from the new control board 110A. The CPU 121 takes out the above-mentioned format-converted data from the RAM 122 and outputs it in response to a request from the old landing / hoistway device 400. As a result, the new control board 110A of the new control panel 100A can communicate with the old landing / hoistway device 400 via the communication conversion board 120 even if the applied communication method is different.

As a specific example, consider the case where the old car device 300 includes an existing old car operation panel. In this case, the new control board 110A communicates with the old car operation panel via the communication conversion board 120. As an example, the new control board 110A gives a display command to the old car operation panel to display information on the display of the old car operation panel by such communication. As another example, the new control board 110A receives operation information from the old car operation panel indicating that the buttons, switches, etc. of the old car operation panel have been pressed by such communication.

The following examples can be considered as specific communication methods of the old communication method and the new communication method. That is, as a first example, it is conceivable that both the old communication method and the new communication method are serial communication methods. As a second example, it is conceivable that both the old communication method and the new communication method are parallel communication methods. As a third example, it is conceivable that the old communication method is the serial communication method and the new communication method is the parallel communication method. As a fourth example, it is conceivable that the old communication method is the parallel communication method and the new communication method is the serial communication method.

As described above, the first division construction step S1, which is one of the series of division construction steps, includes at least the following four steps A1 to A4.
(Step A1) A step of installing a new control panel 100A having a new control board 110A to which the new communication method is applied, separately from the old control panel 100 having the old control board 110 to which the old communication method is applied (process A2). The old hoisting machine 200, which is an example of the first old equipment, has been renewed to the new hoisting machine 200A, which is an example of the first new equipment, and the new hoisting machine 200A and the new control board 110A of the new control panel 100A. (Step A3) A step of replacing the old control board 110 of the old control panel 100 with a communication conversion board 120 that mutually converts the communication method between the old communication method and the new communication method (step A3). A4) Connection between the communication conversion board 120 of the old control panel 100 and the old car device 300 which is an example of the second old device and the old landing / hoistway device 400 which is an example of the third old device. Process to do

When the above steps are carried out, the new control board 110A of the new control panel 100A communicates with the new hoisting machine 200A, and the old car device 300 and the old landing where the communication methods are different are communicated via the communication conversion board 120. -It is possible to communicate with each of the hoistway devices 400.

Therefore, after the completion of the split construction step S1, the new control panel 100A can control the elevator in a state where the old control panel 100 and the new control panel 100A are mixed, and as a result, the elevator is usually in a controllable state. It can be made operable.

(Split construction step S2: Renewal of car equipment)
Next, the split construction step S2 will be described with reference to FIG. FIG. 6 is a block diagram showing a state of the elevator device after performing the division construction step S2 with respect to the state of the elevator device of FIG.

In the split construction step S2, a step of renewing the old car device 300 to the new car device 300A is carried out. Specifically, in this step, the old car device 300 is replaced with the new car device 300A. Subsequently, a step of connecting the new control board 110A of the new control panel 100A and the new car device 300A is carried out.

As described above, the second division construction step S2, which is one of the series of division construction steps, includes at least the following step B1.
(Process B1) The old car device 300, which is an example of the second old device, is renewed to the new car device 300A, which is an example of the second new device, and the new car device 300A and the new control board of the new control panel 100A are renewed. Process of connecting to 110A

When the above steps are carried out, the new control board 110A of the new control panel 100A directly communicates with each of the new hoisting machine 200A and the new car device 300A, and via the communication conversion board 120 of the old control panel 100, It is possible to communicate with the old landing / hoistway equipment 400 having a different communication method.

Therefore, after the completion of the split construction step S2, the new control panel 100A can control the elevator in a state where the old control panel 100 and the new control panel 100A are mixed, and as a result, the elevator is usually in a controllable state. It can be made operational.

(Split construction step S3: Renewal of landing / hoistway equipment)
Next, the split construction step S3 will be described with reference to FIG. 7. FIG. 7 is a block diagram showing a state of the elevator device after performing the division construction step S3 with respect to the state of the elevator device of FIG.

In the split construction step S3, a process of renewing the old landing / hoistway equipment 400 to the new landing / hoistway equipment 400A is carried out. Specifically, in this step, the old landing / hoistway equipment 400 is replaced with the new landing / hoistway equipment 400A. Subsequently, a step of connecting the new control board 110A of the new control panel 100A and the new landing / hoistway device 400A is carried out.

As described above, the third division construction step S3, which is one of the series of division construction steps, includes at least the following step C1.
(Process C1) The old landing / hoistway equipment 400, which is an example of the third old equipment, was renewed to the new landing / hoistway equipment 400A, which is an example of the third new equipment, and became the new landing / hoistway equipment 400A. , The process of connecting the new control panel 100A to the new control board 110A

When the above steps are carried out, the new control board 110A of the new control panel 100A can directly communicate with each of the new hoisting machine 200A, the new car device 300A, and the new landing / hoistway device 400A.

Therefore, after the completion of the split construction step S3, the new control panel 100A can control the elevator in a state where the old control panel 100 and the new control panel 100A are mixed, and as a result, the elevator is usually in a controllable state. It can be made operational.

When all the above series of split construction steps from the split construction step S1 to the split construction step S3 are completed, the renewal of the elevator is completed. As described above, when the renewal of the elevator is completed, all the devices to be renewed are connected to the new control panel 100A, so that the old control panel 100 becomes unnecessary. It is possible to remove the old control panel 100 that is no longer needed. The timing of removing the old control panel 100 may be, for example, the completion of renewal or the maintenance of the elevator. Further, the communication conversion board 120 of the old control panel 100 can be reused.

The order in which the split construction step S2 and the split construction step S3 are performed may precede. It is not always necessary to carry out all the steps of the split construction step S2 and the split construction step S3, and the implementation of some steps may be omitted.

A hoisting machine is given as an example of the first type of old equipment, a car equipment is given as an example of the second old equipment type, and a landing / hoistway equipment is given as an example of the third old equipment type. However, it is not limited to this. That is, the first old equipment is selected from three types of hoisting machine, car equipment, and landing / hoistway equipment, and the second old equipment is selected from the remaining two types. Then, the third old device may be selected from the remaining one type.

As described above, according to the first embodiment, in the method of renewing the elevator, the first division construction step is a step of installing a new control panel separately from the old control panel, and the first old equipment is the first. The process of renewing to a new device and connecting the first new device and the new control board of the new control panel, the process of replacing the old control board of the old control panel with a communication conversion board, and the old control board Includes a step of connecting between the communication conversion board of the above and each of the second old device and the third old device. Further, after the completion of the first partition construction step, the new control board of the new control panel communicates with the first new device, and communicates with each of the second old device and the third old device via the communication conversion board. By communicating, the new control board is ready to control the elevator.

As a result, it is possible to shorten the continuous suspension period of the elevator during the elevator renewal work period. Further, since the new control panel 100A can be installed independently of the old control panel 100 without removing the old control panel 100, the time required to complete the installation of the new control panel 100A is shortened. be able to. Further, since the old hoisting machine 200 can be renewed to the new hoisting machine 200A after installing the new control panel 100A, the operating performance of the elevator can be improved at an early stage.

Further, in the renewal method described in Patent Document 1 described above, it is necessary to connect the cables of the old car equipment and the old landing equipment to the new control panel. However, when connecting the cable to the new control panel, the type of connector of the cable and the pin number of the connector do not match, so a dedicated harness must be prepared. On the other hand, in the renewal method according to the first embodiment, it is not necessary to connect the cables of the old car device 300 and the old landing / hoistway device 400 to the new control panel 100A. Therefore, it is not necessary to prepare a dedicated harness.
